Braun and Singerman each have a long history in bodybuilding. Singerman, from New Orleans, started hitting the gym when he was 13 and kept working out, even through a cocaine and heroin habit he picked up after dropping out of high school. At 27 he witnessed a friend overdose and die, so he got clean and doubled down at the gym. In 2005, he got a job as a personal trainer and started writing thousands of posts on bodybuilding message boards and eventually became marketing director for Ironmag Labs, a supplements company owned by businessman Robert Dimaggio, who had become notorious for selling sketchy supplements. Singerman convinced Dimaggio to bring on Braun, whom he'd met at a bodybuilding competition, as the company's top sponsored athlete.

Weight gain upwards of 20lbs in 4 weeks is not unheard of with this incredibly potent compound. Although subcutaneous water gain would be minimal, intramuscular water retention should be expected. This is due to inhibition of 11b-hydroxylase and build-up of mineralcorticoids which encourage salt and water retention within the muscles. The most obvious physical effects will be improved vascularity, aggressive muscular pumps, and oily skin.
